' of which the following is a specification.

This invention relates to improvements in brushes for use in marking oraddressing boxes, packages, and devices.

My improved brush is constructed to hold amarking fluid which flows bygravity from a tubular handle through a nozzle or nippleupon a brushwhich extends from the nozzle and forms the fluid-applying element.

In the accompanying drawing, which forms a part of'this application,Figure 1 shows in elevation my improved fountain markingbrush inconditionfor use. Fig. 2 is a longitudinal section through the device.

Referring to the details of the drawing, it

represents a cylindrical tube the lower end ofwhich is threadedinternally and in the upper end is 'fixed an externally-threaded P ug f,which is adapted to be engaged by the tubular cap a when the brush'is inuse.

t represents a nipple a portion of which is externally threaded toengage the lower end of the tubeia and another portion of which isexternally threaded, as at If, to receive a tubular nozzle c The nippleis centrally bored to provide a valve chamber b having a seat which'isadjacent to a passage b; The nozzle c is formed with'a chamber 0 fromwhich leads a passageway a, which extends through the ta ering portion 0The nozzle is also externa ly threaded to receive atip d. The tip (1 isformed with aqtapering bore somewhat larger in cross-diameterthan theportion 0 of the nozzle, thus leaving an annular space between thisportion of the nozzle and the inner walls'of the tip. The tip is alsoexternally threaded at one point to receive the cap a when the brush isnot in use.

Extending longitudinally of the tube is av valve-stem e, on the lowerend of which is fixed a needle-valve e, which controls the passage-waythrough the nipple b. The upper portion of the stem is enlarged andthreaded, as at 6 and such portion engages the .lugf. On the upper endof the stem-a knoll: e? is secured tofacilitate the operation of thevalve.

9 represents the bristles which form the brush proper, and these arearranged around the stems ofv the nozzle and are clamoed in place byscrewing up the tip (1-. I Near the upper end of the tubea" small holeis formed, which is controlled by a cover c ,dpivoted on the tubeadjacent to the hole an having a portion fitting the latter.

lowair to enter, so that the inkwill flow freely to the brush.

The valve controls the quantity of fluid which will flow to the brush.The nipple,

nozzle, and tip are all readilyseparable, so

thatthey may be cleaned-and new bristles inserted: By spreadingythebristles around the tapering nozzle the marking fluid reaches the centerof the brush and is thus distributed to the surface of the bristles,thereby making clean lines, In filling the tube the nipple is unscrewed,the cover closing the hole in the other end t prevent leakage at thatpoint.

I claim In a marking device, a fluid-holding tube having an air-inletopening in its upper end, a closure for said opening, a nip ledetachably secured to the lower endo said tube, said nipple having avalve-seat and a fluidchannel therein,a valve adjustably arranged insaid tube and nipple, a tapering nozz'le de: tachably secured to saidnipple, said nozzle having a chamber and a flu d-passa e formed therein,a brush having portions OI its bristl es surrounding said nozzle, asleeve adjustably mounted on said nozzle and adapted to clamp thebristles around the nozzle, and a cap detachably secured to said sleeveand JOSEPH 'B.
